Hi everyone, I have problems understanding how COPS multiplies color channels by alpha. The same setup in nuke or fusion gives the expected results. What am I missing here with COPS?
I also uploaded the Houdini file with two different setups and I get the same strange result.
COPS don't work as expected

Why is it a strange result? The noise has values between 1 and -1, centered at 0. The 'black' pixels are actually negative. Alpha compositing isn't really meant to be used with negative alpha, so I'm not sure what you expect to see.
ahh thanks man, I was thinking in a nuke way. The noise in nuke is 0 - 1 by default, now that I inspect the image I'm seeing the negative values. Shame on me for not inspecting values. Very bad indeed.
